Abstract

A sectorial sprinkling device for coal mining includes, in the central portion of a cutting drum of a cutting machine, a plurality of concentric piping systems which are connected to water delivery means. An interior piping system is permanently connected to the picks of the shearing disc of the drum, but the other two piping systems open via radial ducts into sectorial chambers whose angular extent corresponds to that of the active sectors of the lateral face of the cutting drum, depending on whether the cutting drum is in the high or low cutting position.
